2 dB is fine for 4 cavities per side. If you are able to get under 2.5 dB
for those 4 cavities when retuned on 2m, I'd say you're doing pretty well.

The loops shouldn't require modification. Are the loops rotatable on this
unit?

Yes, they will likely need to be scaled, but before you go through all of
that work, try it without redoing the harness and see what you get. You can
also add elbow adapters or "connector savers" at strategic locations to
lengthen the cables slightly, at least for testing, to see if it makes an
improvement.
